Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract org.apache.bcel.generic.Instruction.accept.

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.

Parameters
v:Visitor

Visitor object
